Greetings, Utah Owner broken down in Savannah, GA

THE BULL

The Z clutch master cylinder hose is a common fault in these cars, they tend to deteriorate internally pushing all of that gunk into the pump causing it to fail over time
That's a Nissan fault.

Top problems, well... that's convertibles for you especially anything that has angle/proximity sensors

Oil overheating problems... How's your driving? usually these engines wont climb in temperatures unless they've been spirited for a while and since it's your first rodeo it will teach you. Many vehicles overheat their oils and you would never know. Be thankful of that gauge and install a cooler.

The rest..... Well..... Spend a couple of weeks here reading this way you can come up with a plan on the most likely failures of this car so you can get ahead of them.

By the way there is this little penis looking like gasket that will introduce some baldness if you still have hair and it's called the Gallery gasket.
keeping oil temps that high will kill this gasket prematurely as well.
